Ensure you peel of the protective filme, if existing, from the see - through plastic. e) Ear protection. ÿ Head protection when using circuler saw blades. Make sure you know how to stop the engine in an emergency (see the section STARTING AND STOPPING ENGINE). Never use the trimmer when tired, physical indisposed or under the effect of alcohol, certain medicines or other drugs. Be careful of the rotating cutting attachment and hot surfaces on the unit.

3) Prolonged use of this product or other

machines _exposing the operator to vibration may produce Whitefngers disease (Raynaud's Phenomenon). This may reduce the hands” ability to feel and regulate temperature and may produce general numbness. Continual or regular users should therefore monitor closely the condition of their hands or fingers. If any of the symptoms appear, seek immediate medical advice. Always hold the trimmer firmiy with both hands. When working maintain à firm foothold. The trimmer must be used exclusively as recommended (see section SAFETY USAGE)

4) Do not carry the timmer while the engine is

running even for short distances; switch off the engine and carry the unit with the cutting head behind you. When camying the timmer in a vehick, secure it to avoid fuel leakage. Aways empty the fuel tank before transporting the unit ATTENTION: For your safety the blade must be kept at all times in its proper case during transport and storage. Start the trimmer on a flat surface. When staring the unit, ensure you have a fm footing. Make sure the blade or the nylon string head does not touch the ground or any obstacle.

5) PRECAUTIONS AGAINST FIRE: do not operate

the timmer near fie or spiled petrol. Do not run the engine in closed or pooriy ventilated areas.

EXHAUST GASES ARE POISONOUS WHEN

INHALED, THEY CAN CAUSE SUFFOCATION

AND DEATH. After refueling always wipe off any spilled fuel Do not smoke during this operation. Start the engine far away from the refueling area and from fuel containers (minimum distance 3 meters). Do not refuel while the engine is still running.

6) Keep people and animals away from working

area (minimum distance 15 meters). lf somebody should approach ou, turn the engine off and stop the blade or the rotating head (see chapter STARTING AND STOPPING THE ENGINE) as during operation the blade or the nylon string head might project grass, grt, or other debris. The blade is sharp, be careful even if handling it when the engine is off. Wear heawy-duty gloves. Turn the engine off and wait for rotating parts to stop completely before working on the machine or before touching the blade or the string head above all to remove possible entangled material. DO NOT USE THE TRIMMER AT ALL IF THE

SPECIFIED SAFETY GUARD IS NOT FIRMLY

ATTACHED (see sections SAFETY USAGE and

BLADES AND NYLON STRING HEAD

ASSEMBLY). Pay careful attention to safety recommendations as you might put your life or somebody elsess in danger as a result of: a) possible contact with cutting or rotating parts. b) possibilty of projection of various objects.

WARNING: do not start engine if it is not

attached to the shaît as the clutch might disintegrate. For units equipped with à clutch, be sure the cutting attachment stops turning when the engine idles.

C. SAFETY USAGE. This product must be held to the right of the operators body. This will ensure exhaust fumes are directed away from the operator and wil not be obstructed by the operators clothing. If you have not used a trimmer before, spend some time in becoming familar with the controls and method of usage before operation. Check the machine carefully before using it. Make sure that there are no loosened screws, damaged parts or fuel leakages. Replace damaged or excessively worn accessories (blades, string heads, guarde). Ensure all maintenance or repair work is carried out by an authorised service center. NB. In order to maintain performance and safety, be sure to use original spare parts and accessories. Avoid using the trimmer over excessively long periods of time. Excessive amounts of vibration can be harmful.

1) Remove from the working area grit, debris,

ropes, metal parts or any other object which might get entangled around the rotating parts or be dangerously projected. Use only the correct accessory recommended for the type _of vegetation to be cut. Do not let the rotating blade contact any foreign object such as stones, rocks, cans etc. Secure hair to keep it above shoulcer height. Before starting to work fit the harness. Adjust hamess with the buckle so that the timmer is well balanced on your right side and the blade or string head is parallel to the ground. Always maintain a firm foothold and a good balance while using the machine. Do not move backwards while you work as obstacles may not be visible. The fitting of the safety pole barrier is obligatory on units equipped with à delta shaped handle when used with a metal blade. The purpose of this safety pole barrier is to maintain a safe distance between the metal blade and the user under all normal or exceptional circumstances.

2) Hamness ring (B) must never be moved from its

original position to avoid unbalancing the unit. Front handies can be separately adjusted to make usage easier on units fitted with “U" shaped handies.

3) The following accessories can be assembled to

your timmer: a) blade, b} nylon string head. Do not attach any blade to a unit without proper installation of al required parts. Failure to use the proper parts can cause the blade to y off and seriously injure the operator and/or bystanders.

2) WHEN USING À BLADE ENSURE THE

CORRECT GUARD IS FITTED. b) WHEN USING À NYLON STRING HEAD ENSURE THE CORRECT GUARD IS FITTED. When using the unit always hold the front part of the machine (blade or nylon string head) below your waist. NYLON STRING HEAD: Always make sure it has been correctiy assembled and fitted. The nylon head is suitable to cut grass and weeds wherever there might be obstacles like trees, fences or walls: The nylon string head also reduces the likelihood of damaging small plants and trees bark. Only use flexible, nonflament nylon line in the nylon line head as specified by the manufacturer. Never use metali line which could break off and become a dangerous projectile. BLADE: Always make sure it has been correctiy fitteci When fitng or changing a cutting device, ensure you follow the instructions in the section “Blade or nylon string head assembly" with extreme precision. Fit these cutting devices using all and only the parts as described, and in the correct orcler.

4) BLADES: you can cut any type of grass,

brushwood or shrub. Operate the machine Ike a sickle always cutting at full throttle.

5) WARNING: always use a well sharpened blade.

A blade with worn teeth besides providing poor performance might also generate a sudden thrust. This can result in a violent sideways kick caused when the blade touches against wood or solid bodies, such thrust might then cause the operator to loose control of the machine itself. Never attempt to work with a damaged blade but replace it with a new one. THRUST: can occur when using any type of circular blade within the risk area: therefore it is advisable to cut using the remaining area of the blade: CIRCULAR SAW BLADE: it can be used to cut sappling, small trees with a diameter up to 7 cm., to clean shrubs.

WARNING: IF A METAL 24-80 TOOTH BLADE

AND SPARE PARTS INCREASES THE RISK OF ACCIDENTS AND IN SUCH A CASE THE COMPANY IS NOT LIABLE FOR DAMAGE TO PEOPLE AND/OR THINGS. D. FUEL Use only fuel recommended by this manual. This product is fitted with a 2-stroke engine and therefore requires a 2-stroke petrol and oi mix. Use unleaded petrol with a minimum octane rating of 90. Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol The use of sub-standard petrol or oil may reduce performance or reduce the life of certain components. UNLEADED PETROL If using unleaded petrol, you must use a totally synthetic 2-stroke engine oil or branded 2-stroke engine oil, see table. IMPORTANT Always shake the fuel mix container thoroughiy before pouring any fuel mix. Fuel mix properties may deteriorate with time and should be used up within 2 months. We recommend that you prepare fuel mix according to your immediate requirements ony. Never use fuel mix more than 2 months old so as to avoid possible engine damage. WARNING Do not smoke when re-fueling Always open the fuel cap slowly, to release any pressure build up in the tank Re-fuel in open spaces only, keeping away from naked flames or sparks.

SAFE STORAGE OF FUEL

Petrol fuel mix is highly inflammable. Put out all cigarettes, pipes and cigars before working with fuel. Avoid spiling fuel. Store fuel in a cool, well ventilated place, in an approved container specifically designed for the purpose. Never store engine with fuel in the tank in enclosed, poorly ventilated areas, where fuel fumes may reach an open flame, spark or pilot light such as in a fumace, water heater, clothes dryer etc. Petrol fumes can cause an explosion or a fire. Never store large amounts of fuel. To prevent possible restarting problems avoid running the fuel tank dry, This also helps to extend engine life. E. SAFETY GUARD'ASSEMBLY:

The carburetor is adjusted for normal operation during production. The carburetor has three adjustment possibilties: L: The needie screw (L) governs the fuel flow at low speed and also the acceleration from low to full speed. To set low speed screw (L}: close screw (L) turning it clockwise without forcing Cv han open gore 1 ul tu Gounteriocluise

If acceleration is not smooth, open another 1/8 turn to increase fuel flow . H: The needle screw (H) governs fuel flow at high speed (throttle valve fully open) R MAINTENANCE, From time to time ensure all screws are tight. Replace damaged, worn, cracked or warped blades. Always make sure nylon string head or blade have been assembled correctiy (see sections NYLON STRING HEAD and BLADE ASSEMBLY) and blade fastener is tightened.

1) AIR FILTER CLEANING

{at least every 25 working hours). A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum speed and cause high fuel consumption and/or difficult starting Remove filer cover as shown in figure 1. Carefuly clean the inside of filter box. The filter can also be cleaned with compressed air.

2) Every 50 working hours inject the gearcase

with gear grease under high pressure through hole (©).
